Release: Build both script & module files on release, fix the map file

Previously, only script files - the ones in `dist` - were generated during the
release, and the module ones - in `dist-module` - were not generated.

Also, the CDN folder was only populated with script files, now module ones are
also added.

In addition to that, the map file had incorrect file references.

All those issues are now fixed.

Closes gh-613
Ref gh-614
